No, the opposite in fact. Harry, Ron and Hermione kept it to themselves. It is illegal to own a dragon and they didn't want to get Hagrid in trouble. So they secretly helped him look after it and secretly got rid of it.
Keeping dragon eggs and raising dragons was illegal, and the children were afraid that Hagrid would get into trouble.
Dragons are illegal in the wizarding world. They are extremely hard to tame, aren't friendly towards people and set fires. Rubeus Hagrid also lives in a wooden hut.
Dragons are illegal in the wizarding world. Only specialists are allowed to have them and they are kept far away from everybody else. Hagrid was never good at seeing the dangerous side to animals and didn't consider the possibility of injury at the hands of Norbert. He also lived in a wooden house and Norbert loved setting things on fire.
Hagrid
His friends names are Hermione Granger, Ron weasley and Hagrid.
Rubeus Hagrid received the dragons egg from an unknown man in the Hog Head, a pub in Hogsmeade. The man was Professor Quirrell who was trying to get information on how to get past Fluffy and knew that Hagrid really wanted a dragon.
In "Harry Potter and the Sorcerer's Stone," Harry, Ron, and Hermione help Hagrid with his dragon, Norbert, by arranging for him to be smuggled out of Hogwarts. They enlist the help of Charlie Weasley, who works with dragons in Romania, to take Norbert off their hands. The trio manages to sneak the dragon out of the castle and into the hands of Charlie's friends, effectively getting rid of Hagrid's unwanted pet. This helps protect both Hagrid and the students from the dangers associated with keeping a dragon at Hogwarts.
According to the story, dragons exhale fire.
Aragog. The big spider that Hagrid was friends with.
Hagrid hatched a Norwegian Ridgeback dragon named Norberta (previously Norbert, however Charlie Weasley tells him that Norbert is female) Norberta, previously named Norbert, is a Norwegian Ridgeback dragon that Hagrid had acquired as an egg from a mysterious, hooded stranger, who turned out to be Professor Quirrell. Hagrid helps the dragon hatch from the egg. Norbert becomes very dangerous and much bigger in the weeks following, so Harry, Ron, and Hermione finally persuade Hagrid to give her to Ron's older brother Charlie, who is studying dragons in Romania. Harry and Hermione take Norbert up in a crate under Harry's Cloak of Invisibility. In the Deathly Hallows, Charlie Weasley revealed to Hagrid that Norbert was actually female, and had been renamed Norberta. Charlie notes that female dragons are more vicious than the males.
In "Harry Potter and the Goblet of Fire," Hagrid says "I shouldn't have said that" during a conversation with Harry and Hermione when he inadvertently reveals information about the Triwizard Tournament and the presence of dragons. This moment occurs in Chapter 19, "The Hungarian Horntail." Hagrid's slip emphasizes his tendency to be overly honest and sets the stage for the challenges Harry faces in the tournament.
